Description

The The invention relates to a motor vehicle roof, in particular for a large-capacity passenger vehicle, such as Van, Combi or minibus, the motor vehicle roof in particular a Part of the vehicle body can be.

Out DE 198 31 133 A1 For example, a motor vehicle roof is known which has a base roof with a headliner. Within the base roof a roof segment is provided, which extends over the entire width of the base roof and can be pivoted out of the base roof. When closed, the roof segment is flush with the surface of the base roof. In the open state, the roof segment is arranged substantially parallel to the starting position to form a small gap between the roof segment and the base roof, which allows a pressure equalization in the motor vehicle interior in the event that one or more airbags are triggered.

adversely in such a motor vehicle roof, that it is in the movable roof segment is a safety-critical component, that can not be impaired in its function. In particular, in large-capacity passenger vehicles, such as Vans, station wagons or minibuses, this is disadvantageous because such vehicles often for the transport of objects, for example Luggage or bulky items be used. For the functionality in particular for a Mega Passenger Cars it is therefore particularly important that items are also on the Roof can be transported. The possibility However, to transport items on the roof will markedly impaired by an extendable roof segment in an emergency, because in the area of the roof segment for safety reasons no Objects can be transported.

It the object of the invention is to provide a motor vehicle roof, that without significantly compromising safety improves the transport of objects.

The Solution of the problem is carried out according to the invention by the features of claim 1. Preferred developments of the invention are given in the subclaims.

The Motor vehicle roof according to the invention, in particular for a large-capacity passenger vehicle, for example Van, station wagon, vans up to 7.5 t or minibus, is suitable, points a base roof, formed by a headliner of the motor vehicle can be. Furthermore, a roof segment is provided, which is preferably is movable substantially vertically relative to the base roof. in the closed state, the roof segment is substantially, preferably without offset, on the base roof. In the open state is arranged the roof segment spaced relative to the base roof. According to the invention connected to the base roof movable spoiler. The spoiler is in this case kinematically connected to the roof segment, that by the movement of the spoiler opens the roof segment and can be closed, wherein in the open state a additional storage space for holding luggage is trained. The additional storage space has in particular that between the base roof and the roof segment compared to closed state additionally accessible volume on, preferably this volume is covered by the roof segment is. The storage space is particularly dimensioned such that, for example a suitcase taken alone from the additional storage space can be.

Since the spoiler is connected to the roof segment, the roof segment can be opened if necessary by a movement of the spoiler. At the same time prevents the spoiler that driving wind pushes over the open roof segment in the vehicle interior. This increases the comfort of the vehicle occupants and is particularly advantageous when a pressure equalization is to be achieved when triggering airbags, as an unnecessarily high back pressure is avoided. The fact that the roof segment forms a storage space, the transport of particularly bulky items is improved because the object to be transported can protrude during transport, for example, from the motor vehicle interior into the storage space. Although the transport volume increases, aerodynamic drag is not significantly increased by the spoiler. In particular, the spoiler can always protrude only so far from the base roof, as the roof segment is extended, so that an unnecessarily high air resistance is avoided by the spoiler. As a result, the motor vehicle roof can also be used in particular in small cars, sports cars or supercars, where hardly any storage space is provided as a rule. Since the motor vehicle roof hardly increases the air resistance in the closed state, the maximum speed is hardly impaired in specialized vehicles designed for high speeds, in particular sports cars, whereby additional storage space can be created if necessary, if not on the maximum speed but on the available transport volume arrives. Since the roof segment can take such a large distance to the base roof that luggage pieces can be accommodated in the additional volume, it is not necessary outside the car roof on the surface of the roof segment to attach luggage, so that the transport of luggage ver is better.
